Digital video is an electronic representation of moving visual images in the form of encoded digital data.This is in contrast to analog video, which represents moving visual images with analog signals.Digital video comprises a series of digital images displayed in rapid succession.. Digital video was first introduced commercially in 1986 with the Sony D1 format, which recorded an uncompressed ...

Cryptographic methods, apparatus and systems for storage media electronic rights management in closed and connected appliances

A rights management arrangement for storage media such as optical digital video disks (DVDs, also called digital versatile disks) provides adequate copy protection in a limited, inexpensive mass-produceable, low-capability platform such as a dedicated home consumer disk player and also provides enhanced, more flexible security techniques and methods when the same media are used with platforms having higher security capabilities. A control object (or set) defines plural rights management rules for instance, price for performance or rules governing redistribution. Low capability platforms may enable only a subset of the control rules such as controls on copying or marking of played material. Higher capability platforms may enable all (or different subsets) of the rules. Cryptographically strong security is provided by encrypting at least some of the information carried by the media and enabling decryption based on the control set and / or other limitations. A secure "software container" can be used to protectively encapsulate (e.g., by cryptographic techniques) various digital property content (e.g., audio, video, game, etc.) and control object (i.e., set of rules) information. A standardized container format is provided for general use on / with various mediums and platforms. In addition, a special purpose container may be provided for DVD medium and appliances (e.g., recorders, players, etc.) that contains DVD program content (digital property) and DVD medium specific rules. The techniques, systems and methods disclosed herein are capable of achieving compatibility with other protection standards, such as for example, CGMA and Matsushita data protection standards adopted for DVDs. Cooperative rights management may also be provided, where plural networked rights management arrangements collectively control a rights management event on one or more of such arrangements.

Private multimedia network

Private Multimedia Network (PMN) complements, and is an improved alternative to digital videoconferencing and multimedia delivery systems. PMN's desktop and meeting room delivery system is designed to support the exponential growth of enterprise team-based initiatives. PMN provides “one-stop-shopping” for the full multimedia rubric. It delivers user-friendly control and cost/effective TV and broadcast quality videoconferencing and other multimedia services to organizations with “critical mass” campuses and building complexes. Though digital systems dominate the videoconferencing marketplace, PMN's hybrid digital/analog architecture has no digital peer in breadth or quality of service within or between campuses. The novel architecture leverages advances in analog video short-haul technology, digital long-haul technology, and telephony audio and control technology to deliver four-level multimedia services: 1) premise; 2) campus; 3) multi-site; and 4) ubiquitous (any site with ITU compatible multimedia equipment (e.g., videoconferencing) and communication links). On balance, the price/performance afforded by PMN's centralized Telco-based control and audio delivery combined with its decentralized broadcast quality video distribution raise videoconferencing and other multimedia services to a new level of ubiquity. Just as telephones and PC LANs, PMN delivers expensive Boardroom and mobile cart videoconferencing capabilities to every desktop via existing multimedia wall plates. The key phases for this invention are: Lip-synchronization across differing network communication links and protocols; Ubiquitous multimedia service; Cost/effective room and desktop deployment; Telco control and audio; Broadcast quality video; Isochronous Quality; Centralized control and distributed operation; and Interoperable architecture.

Online digital video signal transfer apparatus and method

The present invention overcomes the problems in the existing art described above by providing an online digital video signal transfer apparatus and method. Rental of the digital video signals occurs within an online environment including one or more client computers and at least one network server connected by a communications link to the one or more client computers. The method includes providing access to an online catalog stored within a memory of a network video server computer. The online catalog includes information regarding digital video signals available for rental from the network server computer. Requests are then received from client computers for rental of digital video signals selected from the online catalog for a specified period of time. The requests include electronic payment based on the selected digital video signal and the specified period of time. Once electronic payment is provided, the digital video signal is transmitted to the client computer via communications link. Once transmitted, the digital video signal is viewable by a user of the client computer during the specified period of time. Advantages of the invention include the ability to rent motion pictures without having to provide additional monies for purchase of the motion pictures. In addition, the present invention provides an interface that simulates the actual rental of motion pictures within a video rental store. Moreover, during the specified period of rental, the user is allowed to view the motion picture as many times as desired, thereby simulating the actual rental of video cassettes or DVDs of feature length motion pictures.

Automated audio video messaging and answering system

The invention is an audio-video communication and answering system, where system's properties make it particularly suitable as a Digital Video Messaging System for, amongst other things, answering the door. The elements of the system are a DVMS outside module that is a wireless pocket PC with a proximity sensing, a video camera, a microphone, a speaker, a digital transmitter, a digital receiver, and a keypad; a computerized controller that is a personal computer with components for plaving and recording video and audio media; a DVMS inside module having a screen, a microphone, a speaker, a digital transmitter, a digital receiver, and a keypad; a wireless mode; and a DVMS database application with a graphic user interface. The computerized controller is in communication with a public switching telephone network enabling communication with remote peripheral devices, such as a cell phone, PDA, or computer. The system is based on the Microsoft Windows® Mobile 802.11b to coordinate communication between elements. The database application coordinates responses to prompts and events. The proximity sensor activates the system when the sensor detects the visitor's presence. This then starts a series of prompts and interaction prescribed by the application. The system includes an electrically actuated lock that can be actuated through a code entry or remotely. The system enables a visitor to communicate with an occupant either offsite or onsite, where the visitor never knows the occupant's location, unless the occupant discloses his location.
